Given the primacy of reproduction, same-sex sexual behavior poses an evolutionary puzzle. Why would selection fashion motivational mechanisms to engage in sexual behaviors with members of the same sex? We propose the alloparenting hypothesis, which posits that sexual fluidity in women is a contingent adaptation that increased ancestral women's ability to form pair bonds with female alloparents who helped them rear children to reproductive age. Ancestral women recurrently faced the adaptive problems of securing resources and care for their offspring, but were frequently confronted with either a dearth of paternal resources due to their mates' death, an absence of paternal investment due to rape, or a divestment of paternal resources due to their mates' extra-pair mating efforts. A fluid sexuality would have helped ancestral women secure resources and care for their offspring by promoting the acquisition of allomothering investment from unrelated women. Under this view, most heterosexual women are born with the capacity to form romantic bonds with both sexes. Sexual fluidity is a conditional reproductive strategy with pursuit of men as the default strategy and same-sex sexual responsiveness triggered when inadequate paternal investment occurs or when women with alloparenting capabilities are encountered. Discussion focuses on (a) evidence for alloparenting and sexual fluidity in humans and other primates; (b) alternative explanations for sexual fluidity in women; and (c) fourteen circumstances predicted to promote same-sex sexual behavior in women.

Young children with autism spectrum disorder (ASD) struggle with emotion regulation (ER), which is developmentally preceded by lability/negative affect (L/N), and their parents face unique challenges to parenting and providing assistance. The Stress and Anger Management Program (STAMP) is a cognitive-behavioral treatment designed to address ER deficits in young children with ASD through child skill-building and parent training. The current study evaluated child L/N, ER, and parental confidence outcomes in 4- to 7-year-old children with ASD (N = 23; 19 boys) and their parents randomly assigned to a treatment (n = 12) or a waitlist control group (n = 11). Child L/N decreased, regulation was not significantly changed, and parental confidence regarding the child's ability to manage anger and anxiety increased from pre- to posttreatment in the treatment group, but not in the waitlist group. Implications for future interventions that address ER in children with ASD and their parents are discussed.

This case study illustrates a brief, intensive, cognitive behavioral therapy (CBT) for a young male client with a specific phobia of dogs and comorbid autism spectrum disorder (ASD). CBT has been shown to be an effective treatment for anxiety in children with ASD; however, this work has not often been extended to children with language impairment. This case study presents significant modifications to one-session treatment (OST) for specific phobia to make it applicable to a child with minimally verbal ASD. The intervention included four 3-hr treatment sessions conducted over the course of four consecutive days. Assessment sessions were conducted before treatment, and 1 week and 3 months following treatment. The client’s phobia symptoms decreased following the intervention at both the posttreatment and follow-up sessions. The Reliable Change Index (RCI) was calculated to evaluate changes from pretreatment to posttreatment and follow-up and demonstrated a clinically significant decrease in phobia symptomology following intervention. The results suggest the potential efficacy for a brief, intensive, and concentrated CBT treatment for a child with minimally verbal ASD and a severe phobia.
